CARIBURETOR 0R VAPORIZER PROVIDING MEANS FOR EASY STARTING OF INTERNAL- COMBUSTION ENGINES.

Application filed August 24, 1923. Serial No. 659,162.

To all whom it may concern-.-

Be it known that I, JAMus DOUGLAS darn. a subject of the King of England, residing at 14.2 ri est Street, Durban. Nata-l, Union of South Africa (whose post-o'tlice-address is 142 West Street. Durban, Natal, Union of South Africa), have invented. certain new and useful Improvements in Carburetors or Vaporizers Providing deans for Easy Starting of InternaLCombustion Engines,

of which the following is a specification.

This invention has reference to carburetors and Vaporizers with m ans tor easy start inn of internal combustion engines when using either petrol or low grade fuel and especially the latter.

lhe device is to be placed preferably between the carburetor and the intake pipe of the engine.

Fig. 1 is a section and Fig. 2 is a haltsectional elevation of my invention.

The device consists of two flanges A a. of aluminium alloy or of other suitable metal machined and drilled. The said flanges are machined round so as to facilitate fitting on all types of cars and are separated by the main body of the device.

Viound upon the main body is an element composed ol any modern element wire. he length of the winding to be determined iy the battery voltage of the car to be fitted with the device. allowing the maximum pos sible heat in the induction space internally but. insufficient to reach the flash point of the highest grade motor fuels.

.he element is insulated from the main body by a. sheet of mica or other insulating; medium C and a second insulating sheet is fitted outside the element wire. This is then lagged with asbestos cord E to direct the heat rays internally and a light metal casinp; F is fitted over the whole.

The ends of the element B are brought through the housing being insulated by a bead G and pass through fibre block D secured by set screws J attached to flanges A which block carries the terminal points H to the battery and switch connections.

The device can be arranged also for a single Wire system by grounding one end of element B to one of the flanges AA secured by means of a small set screw.

The switch head is provided with a 10 amp. fuse not shown on drawing.

I, l are the Venturi holes tor the passage of the gas.

I claim 1. A vaporizer attachment for internal combustion engines comprising a. spool of metal having an aperture therethrough. a series of Venturi tub-es arranged in said spool in a concentric circle around said aperture. an insulated electrical element wound round the body of said spool and terminals. I

92. A vaporizer attachment for internal eomluistion engines comprising a spool of metal having an aperture therethroug'h, a series o'l. v enturi tubes arranged in said spool in a concentric circle around said aperture. an electrical element wound round the body of said spool, insulating medium on the outer and inner sides of said element relatively to said spool. and terminals.

3. A vaporize-r attachment for internal combustion engines comprising a spool of metal having an aperture therethrough. a series of Venturi tubes arranged in said spool in. a concentric circle around said aperture. n electrical element wound round the body said spool. insulating medium on the outer and inner sides ot said element relatively to said spool. a lagging of asbestos cord outside the outer insulatingmedium. and terminals.

l. A mporizer attachn'ient "for internal combustion engines comprising a spool of metal havi g an aperture therethrough. a series of Venturi tubes arranged in sa d spool in a concentric circle around said aperture an insulated electrical element wound round the body of said spool. and a te rm in a] l u testimony whereof I have hereunto set my hand in presence of two subscribing; witnesses this 20 day of July, 1923.
